Abstract
The present invention provides a method for controlling a drinking-water supply device, the method comprising: a first step of connecting a guide pipe of a case separable from a cabinet to form a channel through which water moves from the case to the cabinet; a second step of supplying the cabinet with sterile water electrolyzed by an electrolytic module included in the case; and a third step of supplying the cabinet with water which has not passed through the electrolytic module included in the case, wherein the sterilization water and the water are supplied to the cabinet from the case via the guide pipe in the second step and the third step.
Claims11
A liquid dispenser comprising:
- a liquid receiving path;
- a first module connected to the liquid receiving path to change a temperature of received liquid to a first temperature;
- a first valve to open or close a first path for discharging liquid at the first temperature;
- an electrolyzer to electrolyze liquid;
- an electrolysis valve to open and close an electrolysis path through which liquid is supplied to the electrolyzer;
- an electrolysis bypass valve to open and close a bypass path through which liquid is supplied to the guide pipe without passing through the electrolyzer;
- and
- a guide pipe connecting the electrolyzer to the liquid receiving path,
- wherein, during a cleaning operation, liquid passes through the electrolyzer before being received in the first module, and wherein, during a normal operation, liquid bypasses the electrolyzer via the bypass path coupled to the guide path before being received in the first module, and
- wherein a first controller repeatedly opens and closes the electrolysis bypass valve during the cleaning operation.
